Technical Field
[0001] The utility model relates to the field of ore dust vibrating screens, in particular to a dust vibrating screen used for ore mining. Background Art
[0002] Dust vibrating screen is a kind of vibrating screening equipment specially designed for handling materials containing dust or fine particles. Its main function is to screen, grade and remove powdery or fine particles in the industrial production process, while effectively controlling and reducing the flying dust generated during the screening process, protecting the working environment, reducing air pollution and ensuring the health of operators.
[0003] During the ore processing process, in order to separate the dust attached to the surface of the ore, the workers usually use a dust vibrating screen. Before the ore and dust are separated, the workers start the dust vibrating screen in advance, so that the filter on it enters a state of continuous vibration, and then place the ore on the vibrating filter. Under the continuous vibration of the filter, the dust attached to the surface of the ore is separated from the main body of the ore, and the detached dust then passes through the sieve holes of the filter and falls into the collection frame below. However, in the process of ore dust separation, if natural wind is encountered, under the influence of natural wind, the natural wind will sometimes lift up the dust that has just been detached from the surface of the ore again, causing the dust to float. The raised dust is easily inhaled by the workers, which may cause respiratory diseases, and may also cause serious pollution to the surrounding environment, reduce the air quality, and affect the ecological balance.
[0004] In view of the above problems, it is necessary to design a dust vibrating screen for ore mining that can filter air containing dust. Utility Model Content
[0005] In order to overcome the disadvantage that, when encountering natural wind, the natural wind sometimes lifts up the dust that has just been separated from the surface of the ore again, causing the dust to float.

[0006] The technical solution of the utility model is: a dust vibrating screen for ore mining, comprising a frame, a filter, a fixed block, a first spring, a support plate, a motor, a cam and a contact rod, the frame is slidably connected to the filter screen, the frame is symmetrically connected to the fixed block, the first spring is connected between the filter screen and the fixed block, the rear side of the frame is connected to the support plate, the motor is installed on the support plate, the motor output shaft passes through the frame and is connected to the cam, the lower part of the filter screen is connected to the contact rod, the cam is in contact with the contact rod, and also includes a cover plate, a dust extraction pipe, a dust filter box, a filter plate and an exhaust fan, the bottom of the frame is connected to the cover plate, the lower part of the cover plate is connected to the dust extraction pipe, the left end of the dust extraction pipe is connected to the dust filter box, the filter plate is clamped inside the dust filter box, the exhaust fan is installed on the left side of the dust filter box, and the exhaust fan is communicated with the dust filter box.
[0007] As an improvement to the above scheme, it also includes a wedge block, a guide rod, a second spring and a handle. The guide rod is symmetrically connected to the right side of the dust filter box, the wedge blocks are slidably connected to the two guide rods, the second spring is connected between the wedge block and the guide rod, and the handle is connected between the right sides of the two wedge blocks.

[0012] The beneficial effects of the present invention are as follows: through the cooperation of the dust extraction pipe, dust filter box, filter plate and exhaust fan, during the ore dust separation process, if natural wind is encountered, some dust may be raised under the influence of natural wind. At the same time, the exhaust fan is started, and the rotation of the exhaust fan generates suction to suck the dust-containing air into the dust extraction pipe, and then enters the dust filter box from the dust extraction pipe.

[0019] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.
[0020] Example: A dust vibrating screen for ore mining, such as Figure 1-Figure 5 As shown, it includes a frame 1, a filter 2, a fixed block 3, a first spring 4, a support plate 5, a motor 6, a cam 7, a contact rod 8, a cover plate 9, a dust extraction pipe 10, a dust filter box 11, a filter plate 12, a wedge block 13, a guide rod 14, a second spring 15, a handle 16 and an exhaust fan 17. The filter 2 is slidably connected to the inside of the frame 1, and the fixed block 3 is symmetrically connected to the inside of the frame 1. The fixed block 3 is symmetrically provided with fixing holes to stabilize the position of the filter 2. A first spring 4 is connected between the filter 2 and the fixed block 3. The first spring 4 can ensure that the filter 2 can effectively reset when vibrating. A support plate 5 is connected to the rear side of the frame 1. The support plate 5 is used to support the motor 6. The motor 6 is installed on the support plate 5. The output shaft of the motor 6 passes through the frame 1 and is connected to the cam 7. The lower part of the filter 2 is connected to the contact rod 8. The cam 7 contacts and cooperates with the contact rod 8. The contact rod 8 is L-shaped to facilitate transmission. The dust filter box 11 is provided with a filter plate 12, which is connected to the bottom of the dust filter box 11. The filter plate 12 is connected to the dust filter box 11, and the filter plate 12 is connected to the front of the dust filter box 11 for filtering the dust-containing air. The filter plate 12 is made of polyester fiber and has a good filtering effect. A pull rod is connected to the front side of the filter plate 12 for easy removal of the filter plate 12 from the dust filter box 11. The right side of the dust filter box 11 is symmetrically connected with a guide rod 14. Wedge blocks 13 are slidably connected on the two guide rods 14. A second spring 15 is connected between the wedge blocks 13 and the guide rods 14. A handle 16 is connected between the right sides of the two wedge blocks 13 for the convenience of the staff to control the movement of the wedge blocks 13. An exhaust fan 17 is installed on the left side of the dust filter box 11. The exhaust fan 17 is communicated with the dust filter box 11 for generating suction to suck in the dust-containing air and filter it through the filter plate 12.
[0021] When it is necessary to use this device to screen the dust on the ore, the staff starts the motor 6, and the output shaft of the motor 6 drives the cam 7 to rotate. The cam 7 rotates and contacts the contact rod 8, and pushes the contact rod 8 to move upward, thereby driving the filter 2 to move upward along the frame 1. The first spring 4 is stretched. When the cam 7 rotates to a specific position and no longer contacts the contact rod 8, under the reset action of the first spring 4, the filter 2 drives the contact rod 8 to move downward along the frame 1, realizing the up and down vibration of the filter 2. Then the staff places the mined ore on the vibrating filter 2. Under the continuous vibration of the filter 2, the dust attached to the surface of the ore is removed. The dust is separated from the main body of the ore, and the separated dust then passes through the sieve holes of the filter screen 2 and falls onto the cover plate 9 below. During the ore dust separation process, if natural wind is encountered, under the influence of natural wind, the natural wind sometimes lifts up the dust just separated from the ore surface again, causing the dust to float. At the same time, the staff starts the exhaust fan 17. The rotation of the exhaust fan 17 generates suction, so that the dust-containing air is sucked into the dust filter box 11 by the dust extraction pipe 10. After the dust-containing air enters the dust filter box 11, when the dust-containing air passes through the filter plate 12, the dust particles will be intercepted and attached to the surface of the filter plate 12, thereby realizing the separation of dust and air. The clean air after filtering passes through the dust filter box 11 and enters the exhaust fan 17, and is then discharged by the exhaust fan 17, completing the air purification process. The above operation is repeated. When the dust screening operation on the ore is completed, the motor 6 and the exhaust fan 17 are turned off. When the filter plate 12 is used for a long time, a large amount of dust particles attached to the surface of the filter plate 12 cause the surface of the filter plate 12 to be blocked. The staff pulls the handle 16 to drive the wedge block 13 to move outward along the guide rod 14, and the second spring 15 is compressed accordingly. When the wedge block 13 moves to a position where it is out of contact with the filter plate 12, the pull rod is pulled to drive the filter plate 12 outward along the dust filter box 11. After the filter plate 12 is moved and the filter plate 12 is taken out, the staff will thoroughly clean the taken out filter plate 12 to remove the dust particles attached to the surface of the filter plate 12 and restore the filtering performance of the filter plate 12. When the filter plate 12 is clean, the clean filter plate 12 is placed back in the dust filter box 11, and the pull rod is pushed to drive the clean filter plate 12 to move inward along the dust filter box 11 until the clean filter plate 12 returns to its original position. The staff no longer pushes the pull rod and releases the handle 16. Under the reset of the second spring 15, the wedge block 13 moves inward along the guide rod 14 until the wedge block 13 returns to its original position, thereby achieving a firm fixation of the filter plate 12.

Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
